Patented Nov. G, 191?.

Application led June 8, 1917. Serial No. 173,529.

To all 'whom t may concern:

Bc it known that l, JAMES DIXON, a citizen of the United States, and a resident of .tipples, and has for its object to provide mechanism of the character specified for dumping loaded cars, wherein a rotatable cylinderl is provided, carrying holders for loaded and empty ears, and so arranged that allhalf rotation of the cylinder will turn the cars completely over to dump the load, and wherein the loaded cars are run down into the tipple and the empty cars are run down out of the ti ple, giving a downward inclination in bot directions.

A further object of the invention is to provide automatically operated mechanism for lockin0' the carsin the holders and for releasing them when in delivering position, and wherein the delivery means is reversible to permit the cars to be delivered'at either end of the tipple.

In the drawings: l

Figure 1 is an end view of the improved tipple;

Fig. 2 is a side view;

Fig. 3 is a longitudinal section of one of the holders;

Fig. 4 is a section on the line 4 4 of Fig. 3, looking in the direction of the arrows adjacent to the line;

Fig. 5 is a section on the line 5 5 of Fig. 4j l Fig. 6 is a sectional view showing the reversing mechanism Fig. 7 is a bottm plan view of the holder; Fig. 8 is a `perspective view of the slide and the reversible tilting mechanism for the car- Fig. 9 is a top plan lview of a portion of Fig. 8, showingr the holding dogs;

Fig. 10 is a perspective view of one end ofthe switch;

Fig. 11 is a diagrammatic view showing the arrangement ofthe tracks with respect to the tipple.

In the present embodiment of the invention, a suitable shaft 1 is keyed in bearings 2 on a suitable supportinfr frame, and on thi's shaft are mounted disks 4, and the said disks support two similar carriers or holders 5 for the cars, the said holders being 'substantially cylindrical casings having openings 6 at their top for permitting the coal to be discharged when theholders are reversed.

The cylinder has at one end a gear ring 7 which is engaged by a pinion 8 on a counter-shaft 9 ]ournaled in suitable supporting brackets 10, and the shaft has a gear wheel 1l, which meshes with the pinion 12 on the shaft of a motor 13. When the motor is in operation, the cylinder will be turned, turning in the direction 'of the arrows in Fig. 1.

l A gear wheel 14 is arranged concentric with the 'shaft 1, but fixed, and the adjacent end of each holdery 5 is provided with a ear ring 15 meshing with the gear ring 14. he holders are mounted to rotate in the disks 4, and it will be evident that when the cylinder is rotated a half turn, each holder will be rotated a complete turn, moving the car from upright to dumping position and from dumping to upright position.

The improved tipple 1s arranged as shown in Fig. 11, tracks 16, 16a and 17, 17a being provi the tipple and the empty cars from the d for conducting the loaded cars toi` tipple, respectively, and the said tracks arev arranged so that the ears may move toward and from the tipple in either direction. A tiltable section of track 18 is arranged within each holder, and each of the said track sections is provided with oppositely extending journal pins 19, which are journaled'in bearings 20 in the holder. `When the tiltable track section is tilted in one direction, the cars will run out at one end of the tipple, while when the track section istilted in the ropposite direction the cars will run out at the opposite end. f

Each of the track sections is provided near each end with wheels or rollers 21, and these wheels or-rollers engage and rest upon a. movable tilter 22. This tilter is mounted to slide longitudinally of the holder 5, and each end of the tilter has a species of cam 23, the said cams being inclines as shown, and the wheels or rollers 21 of the tiltable track section rest upon the inclined surfaces. The tilter is shifted by a shifter 24 which is secured to the tilter, as indicated at 25, a spacing plate 26 being arranged between the tilter and the shifter. The shifter has a wheel 27 journaled in each end thereof,

`65 Opening 40. It will be and these wheels engage tracks 28 which are secured to thedisks 4. 'lhe holders 5 have openings 29 in their' bottoms, and the spacing plates 26 are in these openings, the arrangement being such that the shifter 24 is outside of the holder,` while the tilter :22 is within the holder. These tracks 2S have cut away portions 30. A switch lever 31 is *pivotally mounted, asindicated at 3:3. between the eut away por` tions of the track, and each end of the lever is provided with a cam or switch head 33, shown more particularly in Fig. 10, and adapted to lill the eut away portions 30 of thetraeks. 'lhese cams are similar, and the lever is angular, so that when one cam is in engagement with a cut away portion of the track, the other cam will be depressed below the said eut awa' v portion. leaving the said cut away portion open. The wheels 2T of the shifter move in contact with the tracks, and it will be evident that when the shifter strikes the eut awayportions it will he moved .longitlulinally in one direction, dependent upon the position ot' the lever 3-1'7 A handle 34 is connected with one of=the cams. for swinging the lever, so that the shifter mavbe moved in either direction.

Then the shifter is moved as indicated in Fig. 6. the'tilter will be moved `therewith. and will tilt the car, one of the wheels` 21 rolling down the incline or canr'23, while the other wheel rolls up to the. high part of the said cam. 4lVhen `tlie car is released, it will be evident that it will roll out of the holder and down the track.

Mechanism is provided for automatically locking the car as it moves on to the tiltingy track section and for releasing thebsame after it has been dumped. The said mechanism comprises a pin which is held in spaced relation below the bottom of the car and at the center thereof by substantially A-shaped brackets 36,. the bases of the brackets being secured to the car, witlrthc apiccs below said support the pin. This pin is adapted to 4engage beneath one of the arms of a T- shaped anchor 37 which is connected Vwith the tilting track section in line with the journal pins 19 and between the same. As the car comes on' to the tilting track section from eitherdirection the pin 35 will move beneath the adjacent arm of the anchor, and locking means are provided for locking the pin beneath the anchor at either side thereof. Each of the said means comprises a latch plate 38. each plate heilig pivoted at 39 tomthe tilting track sect-ion in a 60 slot in the. said section and each plate has a rounded opening 4,0 for receiving the pin, and a tail 41 for enga ing a dog 42 in theI shifter to hold the plate in `substantially vertical position, with the pin 35 in the evident from an in- A the pin will move into the ter with the tracks 16and 1G.

' figure,

ar, and the said apices spection of Fig. 3 that as long as the latch plate isheld in this position the pin cannot become disengaged. Normally, thelatch plates hold the position at the right of the anchor in Fig. 3, `the latch plates 'being weighted to assume this position when released. lVhen a car isrun on to the track section, with the latch plate in the position shown at'the right ot' the anchor in Fig. :5, lopening l() and will swing the latch plate upwardly into the position at the left of the anchor. The dogs 42 are pivoted in an opening 43 in the tilter' on a common pivot indicated at 4l, and they are normally pressed upwardly into engaging position by coil springs 45 arranged beneath the dogs.

Referring to Fig. 3, -it will be seen that as long as the tilter is in the tull line position of thcsaid figure the operative latch plate will be held in engaging position by the adjacent dog. When however, the tilter is shifted into the dotted line position of xlfig. 3 the latch plate will be released by the dog, and gravity will cause the car to run oli' the tiltable track section, which will be tilted by the shifting of the tilter.

In operation, the loaded cars 46' are run down the` tracks 16 and 16 into that holder which has its tiltable track section in regis- 9 'lhe motor will rotate the cylinder, moving the loaded car from the position at the right and bottom of Fig. l to the left and top of said and turning the car completely over during the movement to dump the load. As thecar comes-into the last named position, the shifter JWill'be shifted to shift thetilter and release the latch plate. and the ea r will roll out at-one end of the tipple. depending upon the position of the switch lever 31. Locking pawls 47`are piv ed to .the frame-work 3, andthese pawls engage nptches48 in the adjacent disk to prevent r'evgrse movement of the cylinder. ,These 11@ paw/'ls hold the cylinder in locked position until the empty car is run oil and the loaded ear is run in. A clutch +9 is provided for `connecting the counter-shaft with the pinion 8and the said cluteh is operated h v a 115 lever 50. But little power is required to turn the cylinder` sineethey weight of the empty holder assists` in lifting the loaded ear,and the.v loaded car is dumped after a quarter turn. i

It will be noted that the shaft' 1 is keyed to`the support 3 andthe bearing. while tho gear wheel l't Vis secured to the shal't. the shaft and the gearwvlieel being stationary with the supporting frame. 'lhe pawls` ti 125 are keyed to a shaft 5l journaled in the supports 3, and they are operated b v `the tipple operator by means of a lever 52 pivoted to an are shaped support 5i! aml connect-ed to a` dependingarm 5ft on the shaft by means 130 of a link 55. The pawls 47 do not require to be operated, being spring-pressed into place. v
